XRISM Spectroscopy of the Stellar-mass Black Hole 4U 1630-472 in Outburst

We report on XRISM/Resolve spectroscopy of the recurrent transient and well-known black hole candidate 4U 1630−472 during its 2024 outburst. The source was captured at the end of a disk-dominated high/soft state at an Eddington fraction of λ _Edd  ∼ 0.05 (10 M _⊙ / M _BH ). A variable absorption spe...
